Central and South Algeria. 



Before proceeding to rectify the three .serious errors into which I had fallen 

 I should lilce to pomt out the reason whj' I gave no diagnosis of the two new 

 names given in this table. I concluded that the giving of the prefix gen. aest. 

 and gen. vem. was sufficient diagnosis, for the difference between spring and 

 summer generation is the same in all subspecies, i.e. the summer brood differs 

 from the spring brood in all cases by larger size, more creamy upperside, and 

 the green pattern on the underside more " run " and irregular, while the green 

 is strongly suffused with yellow, whereas each generation of one subspecies differs 

 from the corresponding generation of the typical race by the same differences. 



Now, the fu-st error I committed was not to read carefully Ribbe's description 

 of his alhawhra. If I had done so, instead of applying the name merely from 

 the locality to summer Andalusian specimens received from Ribbe, I should 

 have discovered that alhambra was applied to an aberration with reduced white 

 spots and increased green markings of both spring and summer generations 

 of crameri. This necessitates giving a name to the Spanish and North African 

 summer brood, and I propose to call it butleri ; so that this subspecies must 

 stand in the table as follows : 



Euchloe ansonia crameri Butl. 



gen. vern. cra7neri Butl. 

 gen. aest. butleri Rothsch. 

 Spain and North Africa (north of Atlas). 



The second mistake I have made is that I read too hastily the synonymy 

 under Euchloe crameria in the Catalogue of Diurnal Lepidoptera described by 

 Fabricius, or I should have seen that, whereas I thought Mr. Butler was here 

 renaming Cramer's belia ox Asia Minor, crameria is only a misquotation of the 

 name crameri given to a specimen labelled " Germany, J. J. Becker," but really 

 from some part of the Iberian peninsula. 



Thus here again the spring brood of the Asia Minor race (which is belia 

 Cram, (type locality Smyrna)) requires a new name, and I propose the name 

 originalis for it. This Asia Minor subspecies will therefore have to be altered 

 m the key to : 



Euchloe ausonia taurica Rober. 



gen. vern. originalis Rothsch. 

 gen. aest. taurica Rober. 



Asia Minor. 



The greatest mistake, however, which I perpetrated is in connection with 

 the Central and South Algerian form ; and as I had been special!}' studying this 

 race I consider my error most unjustifiable, even though tlie .synonymy of the 

 North African races was so entangled. Fir.st of all, from the fact that most of 

 ray May specimens of Algerian ausonia are already belonging to the summer
